Applications are invited for a 3.5-year fully-funded PhD studentship in the development of semiconductors for next-generation solar cells.
With a fast developing of the internet-of-things, wireless sensor networks deployed in a variety of environments for home automation, health monitoring, environmental control and industrial processes tracking are becoming a permeating technology. A necessary requirement for these small sensors and networks is energy autonomy. An energy-storage component is critical to store energy harvested from renewable sources to ensure energy supply over prolonged periods of time. Microsupercapacitors with high efficiencies over small footprint areas would benefit these applications. To date device miniaturization has been developed to achieve mainly planar-geometries. 3D printing offers the opportunity to fabricate devices with different architectures and to develop those over the vertical direction. The objective of this project is to fabricate microsupercapacitors via a 3D printing technique based on continuous extrusion of a viscoelastic ink. The materials of choice are 2D atomically thin transition metal dichalcogenides (TMDs) in their metallic polymorphism (1T/ 1T’ phases) which are promising for energy storage applications. The project will involve inks formulation, 3D printing of electrodes and current collector, detailed characterisation using advanced microscopy and tomography methods to determine the microstructure and the 3D ordering of the platelets and to design and evaluate devices. Advanced spectroscopy characterization will be also utilized to study chemical composition and crystal phase. Upon device evaluation, microstructure design and the ink formulation will be modified to optimize energy density and power density of the microsupercapacitor.
The ideal candidate for the role will have received a First-class Honours degree in Materials Science, Chemical Engineering, Electrical Engineering, Chemistry, Physics, or a related discipline. The project will be supervised by Dr. Cecilia Mattevi in the Department of Materials. Her lab is based in the South Kensington Campus with access to facilities at the Sir Henry Royce Institute, located in Imperial’s White City campus.
Funding Notes: The funding will cover tuition fees plus a maintenance stipend of £17,009 (this year’s rate) per annum for UK Students as well as EU Students resident in the UK for 3 years.
